device/arm: clear pending interrupts before enabling them

Browse Source 
Without this change, a pending interrupt would spuriously trigger
immediately after enabling. This happens if an interrupt is triggered
during flashing (e.g. by DMA), which survives the subsequent reset.

This behaviour matches e.g. `machine.irqSet` in machine_rp2_rp2350.go.

See 7f970a45, whose symptoms were likely caused by spurious interrupts.
